Alight on the Wings Of Legend
Branc Valreik
aka The Killing Fields
aka Breath of Death (modern)
female
a demon/green dragon
She at one point laired in the mountains on ‘goliath island’ and is believed to still do so.
In modern times she has exhibited necrotic powers in addition to her typical poison. It is theorized that exposure to the effects of the heart of death both weakened her and is the source of these powers.
She apparently retreated to the Elemental Chaos after the battle over Shacrenzal. Her currently location is unknown, other than ‘back from the Elemental Chaos’ (1/4/15)
